As Jamie Foxx's FLOTUS in the new action flick White House Down (which hits theaters tomorrow!), Garcelle Beauvais definitely ranks as one of the most bodacious First Ladies we've ever seen in film. Check out the actress in these cropped, peg-legged jeans. Those are not easy to pull off, yet Beauvais rocks 'em with ease. Jealous yet?

"She's got a butt to be envied, for sure!" agrees her trainer Miguel Novo from Body Sculpt Studio. "Her legs are also a great attribute." (We say, "Duh!") According to Novo, Beauvais keeps her bangin' body in such fine form with help from resistance training exercises like hamstring curls. But even better, turns out she also manages to keep up a super sunny disposition while sweating with Novo. "Working out with Garcelle is like working out with your best friend," he says. But is everyone's BFF starring in the latest action blockbuster to hit Hollywood? Double jealous.

Come down to all fours on the yoga mat with your forearms pressed against the mat. Place a 10-lb. dumbbell on top of the back of your knee (or a lighter weight if you need to take it down a notch) and squeeze firmly to hold it in place. From this position you will raise your leg up as high as you can with a strong pause at the top, then slowly drop the leg down to the mat. Make sure you keep your leg pressed tightly against the weight through the entire movement. After completing 15-20 repetitions, hold at the top for a total of 30 seconds. Do between 3-4 sets on each leg.
